I fail to see any problem. If you want your function to return a fixed
number
of values, then write it so. If you want to return a variable amount of
results,
then the builtin function unpack() of Lua 5 and a table will help you.
For example, in Lua 5 beta you can say:
function varres(nres)
t = {};
for n = 1,nres,1 do t[n] = n; end;
return unpack(t)
end
print(varres(1))
1
print(varres(3))
1 2 3
print(varres(7))
1 2 3 4 5 6 7
You could even say: return a,b,unpack(optresults)
To return both a fixed and a variable amount of arguments.
So I see no reason for the change you propose.
